I installed the Arnott 13 in. Black Bilstein Rear Air Suspension System on my 2010 TG, Price $599.00. The best money I have spent on my TG! The install was simple and the ride is so smooth. I mounted the air compressor in the trunk, out of the weather and the way. I made my mounting bracket out of alumn angle iron, this is the only part that I had to make. It takes up very little space. When you look at their sight you won't find a listing for the TG, look under the Harley Touring section and you will find the 13 in. system. We have a 1200 mile trip planned this weekend. If it makes any difference my wife thinks the ride is smoother than her Accord. Call Arnott and talk to Bill, he will answer any questions you have.
